PNEUMATIG TIRE.

Application iled May 4; 1909. Serial No. 493,837.

To all wwm it may concern:

Be it known that I, MILTON T. J. OoHs,

Y a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Pneumatic Tire, of which the following is a specification.

. This invention relates to pneumatic tires of that type composed of independent sections whicli intercominunicate through an annular air channel in the felly of the wheel. The invention has for its principal object to provide a tire of this character which is of comparatively simple and inexpensive construction, reliable and efficient in use in minimizing the shocks transmitted to the vehicle and possessing good wearing qualities, in connection with a simple and effective A means for attaching the sections to the felly in such a manner as to admit of ready repair in case of puncture. Q

With this and other objects in view, the invention comprises the various novel features of construction and` arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a fragmentary side view of a wheel equipped with the tire, parts of the latter being shown in section.` Fig. 2 is a transverse section-on line 2 2, Fig. 1. Fig. 3 is a perspective view of one of the clamping plates for the tire sections. Fig. 4- is a fragmentary perspective view of the base portion of one of the tire sections. Fig. 5 is a modifiedform of tire. Fig. (3 is a transverse section thereof. Fig. 7 is a perspective view of the interlocking end of the air tube.

Similar reference characters are employed to designate corresponding*parts throughout the views. A

Referring to the drawing, 1 designates the wooden felly ofthe wheel to which the tire is secured, the telly being supported on spokes 2 in any approved manner. Surrounding the felly 1 is a tire-holding ring 3 which is formed with parallel side flanges 4 whereby an annular channel 5 is provided.

y, Fitted in the chamber is a ring 6 having in- Hardly-extending anges 7 bearing against the side flanges 4, whereby an air-containing chamber is provided around the' wheel. The

flanges 4 project beyond the outer ring section-6 and are formed with marginal beads 8 having undercut inner, faces to provide shoulders into engagement with which marginal portions 9 on the tire sections 1() are compressed. The tire sections 410 are in the form of vhollow blocks of rubber or other re- 4silient material closed at the ends by walls 11 and open `at their bases. These tire sections, which are arranged end to end and extend entirely around thewheel, have inwardly-extending base webs 12vat all sides and bearing against the outer surface of the rin 6. These webs 12 yafford means for securing the tire sections in place by approximately rectangular clamping plates 13 which are substantially eoextensivel with the area of the chamber of each tire section, and they bear on the webs 12 to clamp the same against the ring 6. The inner face of plate 13 is cut away at its edges so as to provide a raised central portion v13 and a marginal so that the flange will bite into and thus obtain a better grip on the base web of the tire section. Each plate thus has two portions which bear respectively against the outer -face or wall of the ring or tube and a ainst the base web of the tire section. The c ampingl plate serves as a spreader for forcing the portions 9 of the tire sections into the seats 8 on the flanges 4 so as to assist in retaining the tire sections in place. Each clamping plate 13 has a central boss 16 which passes through a slot17 in the ring 6, the boss having a non-circular openin 18 for receiving a correspondingly-shape bolt 19 that passes through the inner ring section and felly of the wheel for clamping the tire sections to the wheel and to hold the parts of the tire together. Leakage around the bolts19 is lprevented by rubber or other gaskets 19a between the telly and air tube and between the felly and nuts of the bolts. The flanges 4 and 7 of the rings 3 and-6 may be brazed or welded together to thereby prevent leakage of air from the channel The chambers of the various tire sections are in open communicationV with the common channel 5 so that air can pass freely one to theoth'er, and for this purpose, ports 9.1 are provided in the clamping plates 13, which ports communicate with the ports 17 of the ring 6. Airv is supplied to the channel or air tube 5 by an ordinary valve device 9.2 to

`flange. 14 which has its inner face inclined l which a pump can be attached. lNitli a tire f I 45 vide two or more bolts 27 for each penses with the necessity of carrying extra i tires for emergency urposes. Furthermore, a reliable and r 'ent tire is provided and one which possesses good wearing qualities. It is observed that the clamping plates are flat on their outer faces, so thatv in case it is necessa I deiiated, t ere will be nov d erous wear on the tire sections, since the at faces of the clam ing plates prevent cutting.

In ordlir to adapt the tire for wheels already in use, the air tube, instead of being made continuous, .as would be the case in the original manufacture of the wheels, will be split at one point so that the tube can be enlarged Vor contracted to lit the rim 26 of the wheel to'which it is to be applied. Automobile wheels alread in use are usuall of standard size but t ey may vary slight y in their peripheral dimensions, so that the air tube will have to be designed for accommodating itself to such variations. For this purpose, the construction shown in Figs. 5 to 7 is provided, in which the air tube 23 is constructed of a single piece of tubular metal manufactured in any desired manner and having its ends interlocked in such a manner as to ac-V commodate the tube to a wheel'rm. For this purpose, one end of the tube is provided with asocket 24, while thel other end is formed with a tongue 25 that slidably engages in the socket, the ends of the tube, of course, being closed to hold air. The l air tube is a plied to the rim 26a of' the wheel and hel 1n place by the same bolts, 27, which hold the tire sections 28 in place. All

' that will be necessary in e nipping a; wheel with the improved tire is t e making of the holes in the felly 26 and rim 26 for receiving the bolts 27. The tire sections 28 may be of any desired length, and in order to e ectively retain them in place on the-air tube and engaged with the hollow beads or flanges 30 thereof, it will be necessary to proclamping plate 31, the clamping a plate 'being of the same general constructlon as that shown in Fig. 3, except that more bolt-receivin bosses 32 and air ports 33 are provide The bosses 32 en 'age in o enings 34 in the outer peripheral ace' of t e air tube. The air tube is provided with orts 35 which aline with the orts 334so that free communication is a orded between the air tube and chambers of the tire sections.

From the foregoing description, taken in connection with the accompanying drawings, the advanta es of the construction and ofthe method o operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation `o f the invention, together with the device which I now consider to be the best embodiment' thereof, I desire to haveit understood that to run the vehicle with the tire` the device shown is merely illustrative, and that such changes may be made when desired as are within `the scope of the claims ra ended hereto.
